If you want to increment a numeric value which is being presented as text, you need to convert the text to the appropriate numeric value, increment it, then convert it back to a textual representation. To restrict the operation to days, only, take the first two characters as a unit, convert to numeric, increment, convert back.

You might wish to investigate the various capabilities offered by the libraries. There are a number of date/time manipulations that one can do.
